TECHNICAL FIELD

The present invention relates generally to methods, systems, and apparatuses for a learning-based framework for personalized imaging quality evaluation and optimization. The disclosed methods, systems, and apparatuses may be applied to, for example, imaging modalities in the medical imaging field and others.

BACKGROUND

Imaging devices such as Magnetic Resonance Imaging (MRI) scanners provide myriad options which refine image acquisition or processing procedures based on feedback from the user. In order to provide meaningful feedback, the user must be able to articulate his or her concerns in terms of image quality. However, image quality is a fuzzy notion. It varies with the modality, the use-case, and the customer. There are several steps in the imaging and rendering chain which have parameters that can be tuned to affect image quality, but finding the right tuning requires solving two challenging problems. First, since there is not an established description standard for image quality, it is challenging for users to comment upon, or suggest modifications to, image data or its related parameters. Secondly, even when the customer requirements are known, determining the optimal parameter settings may be difficult. For example, a particular change to an image characteristic may require changes to several, unknown parameters.

Moreover, the act of getting feedback on image quality is very much of an art. For example, often a service engineer must visit the customer site and proceed by trial and error: dialoging with the customer to try to understand their problem, tuning the parameters, showing the result to the customer, and iterating until the customer is satisfied with the result. This process is time intensive and wastes resources. Accordingly, it is desired to create a technique for gathering image feedback which may be automated, but still personalized, to address the issues set out above.

SUMMARY

Embodiments of the present invention address and overcome one or more of the above shortcomings and drawbacks, by providing methods, systems, and apparatuses related to a learning-based framework for individualized image quality prediction and optimization.

According to some embodiments, a computer-implemented method for providing image quality optimization individualized for a user includes a computer receiving raw image data acquired from an image scanner and identifying one or more raw image quality features based on the raw image data. The computer automatically determines one or more target image quality features by applying one or more user preferences to the one or more raw image quality features. The computer also automatically determines one or more processing parameters based on the one or more target image quality features. The computer may then process the raw image data using the one or more processing parameters to yield an image.

The aforementioned method may be refined, supplemented, or otherwise modified in various embodiments. For example, in some embodiments, the method further includes providing the image to the user in a feedback interface which allows the user to associate a preference indicator with the image. This preference indictor may be, for example, a binary tag set to one of an accept value or a reject value and/or a numerical value selected from a range of numerical values. The feedback interface may be further configured to identify new image quality features based on the preference indicator. The target image quality features may then be modified based on the new image quality features. In some embodiments, the processing parameters are determined using a deep learning network (e.g., an artificial neural network) where the target image quality features are an input. The raw image data and/or the one or more raw image quality features may be used as an additional input to this network.

According to other embodiments, an article of manufacture for providing image quality optimization individualized for a user comprises a non-transitory, tangible computer-readable medium holding computer-executable instructions for performing the aforementioned method, with or without the additional features discussed above.

According to other embodiments, a system for providing image quality optimization individualized for a user includes an image scanner configured to acquire raw image data and a computer comprising one or more processors. The computer's processors are configured to (i) identify one or more raw image quality features based on the raw image data; (ii) determine one or more target image quality features by applying one or more user preferences to the one or more raw image quality features; (iii) determine one or more processing parameters based on the one or more target image quality features; and (iv) process the raw image data using the one or more processing parameters to yield an image. In some embodiments, the system further includes a feedback interface configured to present the image to the user and receive a preference indicator associated with the image from the user. The computer's processors may be further configured to modify the user preferences based on that preference indicator.

Additional features and advantages of the invention will be made apparent from the following detailed description of illustrative embodiments that proceeds with reference to the accompanying drawings.

DETAILED DESCRIPTION

Systems, methods, and apparatuses are described herein which relate generally to the automation of personalized parameter tuning for imaging applications. Briefly, a database of imaging device information is leveraged and big data methods are applied to learn what the customers want directly from them. The disclosed techniques are able to prescribe default parameters to fit each user's preferences, allow the user to fine tune those parameters intuitively on his own, and learn from the user's own tuning to refine the default parameters. The examples presented below illustrate the applicability of automation of personalized parameter tuning in the context of Magnetic Resonance Imaging (MRI). However, it should be understood that the techniques described herein may be generally applied to various imaging modalities, in the medical imaging field and others.

User preferences for image processing are non-linear and non-physical. Any model is bound to be complex and only able to be validated empirically. Additionally, these preferences are dynamic in the sense that they can change over time. The feature space to represent image quality cannot be known a priori. To address this lack of knowledge, the systems, methods, and apparatuses described herein apply deep learning techniques.

FIG. 1 provides an overview of a learning-based framework 100 for individualized image quality prediction and optimization, according to some embodiments. The initial input to this framework 100 is Raw Image Data 105. In some embodiments, this framework 100 is implemented in a live system on a computing device directly connected to the image scanner that acquires the Raw Image Data 105. In other embodiments, the Raw Image Data 105 may be acquired from a database or other computer readable medium storing previously acquired data.

The Raw Image Data 105 is processed by a Raw Image Quality (IQ) Feature Determination Component 110 to determine non-linear statistics, referred to herein as IQ features, associated with the Raw Image Data 105. Examples of IQ features include the brightness, the contrast, resolution, and amount of noise present in the image data. These IQ features provide a standardized qualitative tool to described image quality.

In some embodiments, the raw IQ features are automatically determined by the Raw Image Quality (IQ) Feature Determination Component 110 using any technique generally known in the art. For example, the Raw Image Quality (IQ) Feature Determination Component 110 may be pre-configured with a list of IQ features and algorithms for determining values for these features based on the image data. In other embodiments, the Raw IQ Feature Determination Component 110 automatically extracts the raw IQ features from metadata associated with the acquisition of the Raw Image Data 105. This metadata may be provided in the Raw Image Data 105 itself or, alternatively, in one or more associated files. In other embodiments, the individual that acquired the Raw Image Data 105 may manually supply the raw IQ features via interaction with a graphical user interface (GUI) providing functionality for the Raw IQ Feature Determination Component 110. In other embodiments, the method to extract the raw IQ features is learnt from a database of images. This learning can be supervised (i.e., the numerical values of the raw IQ features of the training images are known), unsupervised (i.e., the numerical values of the raw IQ features of the training images are not known, and the quality of the raw IQ features is inferred from the user satisfaction with the whole system), or semi-supervised (i.e., the numerical values of the raw IQ features is known for some of the training images, but not all of them.)

The raw IQ features are used as input to a User IQ Feature Recommendation Component 115. The User IQ Feature Recommendation Component 115 transforms the raw IQ features derived from the Raw Image Data 105 into a set of target IQ features which are individualized for a particular User 120. Ideally, the number of target IQ features should be relatively small and highly correlated with image quality.

The User IQ Feature Recommendation Component 115 may be implemented via a deep learning network such as, for example, an artificial neural network. The deep learning network may be trained based on the past behavior of the User 120 when operating the imaging system. This deep learning network may be trained using supervised or unsupervised methods. In some embodiments, each user is surveyed with a set of pre-generated images and the User 120 identifies adjustments to image features. This survey may be conducted in an interactive way. For example, the user may be presented with each image in a graphical user interface and be allowed to adjust sliders or some other graphical component to indicate changes to IQ features. In embodiments where unsupervised techniques are used, the deep learning network may be trained based on the feedback provided to the User 120. For example, by comparing the IQ features associated with images rejected by the user with the IQ features associated with images deemed acceptable by the user, a set of preferred IQ features can be learned over time.

Continuing with reference to FIG. 1, the Raw Image Data 105 and the target IQ features determined by the User IQ Feature Recommendation Component 115 are processed by a Parameter Recommendation Network 125 to identify image processing parameters. This allows the user to tune IQ features rather than specific parameters that may be used to achieve those features. The Parameter Recommendation Network 125 is implemented as a model trained with images processed with different parameters and their IQ features. This model effectively maps a set of IQ features to parameters which may be applied to the image scanner. The exact parameters that are determined by the Parameter Recommendation Network 125 will vary depending on the imaging modality and the capabilities of the specific image scanner used for image acquisition.

One or more deep learning models generally known in the art may be used to implement the Parameter Recommendation Network 125 within a supervised or unsupervised learning paradigm. For example, in one embodiment, the Parameter Recommendation Network 125 is an artificial neural network. In the example of FIG. 1, the Parameter Recommendation Network 125 has two inputs: the target IQ parameters (determined by the User IQ Feature Recommendation Component 115) and the Raw Image Data 105. However, the full image may not be required to estimate the right parameters. Thus, in other embodiments, the inputs may be the raw IQ features (determined by the Raw IQ Feature Determination Component 110) and the target IQ features.

The Processing Component 130 uses the parameters determined by the Parameter Recommendation Network 125 to processing the Raw Image Data 105. The Processing Component 130 may implement any of a variety of specific image processing algorithms generally known in the art for the particular imaging modality being supported by the framework 100. The results of processing by the Processing Component 130 are the Processed Image(s) 135.

In FIG. 1, a feedback loop is utilized wherein the Processed Image 135 is presented to the User 120 in a graphical user interface (GUI) which is configured to monitor the response of the User 120 to the image. For example, in some embodiments, the GUI may be provided by a proprietary tool such as Siemens CLEARChoice. Based on the response of the User 120 to the Processed Image 135, the operation of the framework 100 may be modified. For example, the response of the User 120 can be used to refine the IQ feature transformations performed by the Raw IQ Feature Determination Component 110. Additionally, the response may be used to generate training data with synthetic labels for the User IQ Feature Recommendation Component 115. This concept may even be extended such that the responses from a large population may be aggregated and users can be clustered based on their individual responses.

In some embodiments, the response of the User 120 to the Processed Image 135 is provided in the form of a preference indicator. For example, in some embodiments users provided a preference score, while in other embodiments a simple accept/reject tag is used. Although the preference score provides the benefit of allowing the user to specify preferences within a range of values, the binary tag may be more efficient in embodiments where user preference is modeled as a classifier learning program. Thus, a binary classifier can be learned that would accept the same changes as the user. Moreover, in some embodiments, the user's preferences may be inferred based on actions related the image performed outside of the outside of the feedback interface. For example, the user's reactions to the image (e.g., saving, discarding, etc.) may be used to infer acceptance or rejection of the image.

Note that there is a bootstrapping problem associated with the framework 100 illustrated in FIG. 1. Specifically the Parameter Recommendation Network 125 is needed to gather large scale training data, but the IQ feature transform must be learned to build the Parameter Recommendation Network 125. To train the IQ features several user responses (ideally, many more than the number of features) are needed. To address the bootstrapping problem, in some embodiments, the framework learns from simulated users. The simulated users are configured such that their preferences remain consistent across images. Various techniques may be used for creating the simulated users. For example, in some embodiments, Product Specialists use their expertise to simulate users manually (possibly, also simulating different quality characteristics across different vendor image scanners). In other embodiments, recognizing that different scanners have different responses, the output of different scanners is used to simulate users. For example, one group of simulated users may prefer the default parameter settings for a particular scanner. In other embodiments, a testing panel is used. In other embodiments, learning is performed on images with known deformations or degradations with users modelled by decision rules. Additionally, two or more of the techniques discussed above may be used in combination to create the synthetic users.

To provide a more detailed example of synthetic user creation, consider a set of pre-generated clinical images. These original images are initially designated as “the gold standard” that all users would accept. For each image, a group of degraded images are generated with various degrees of blurring, motion, noise, etc. The exact degradations may vary, for example, based on their relevance to the modality used to acquire the images. Different users may then be modeled by different sensitivities to the degradations: i.e., from a given degraded image, which images in the same group will the user accept? Note that no user input needed for this technique and clinical images can be re-used at different degradation levels.

FIG. 2 shows a process 200 which applies the framework 100 shown in FIG. 1 to provide image quality optimization individualized for a user. This process 200 may be implemented, for example, on an image processing computer associated with image scanner in a live setting or, alternatively on an offline computing system which is able to communicate parameters to the image processing computer.

Initially, at step 205, raw image data received, either directly from the image scanner that acquired the data or via retrieval from a data base storing previously acquired data. The imaging modality associated with the raw image data should be known, or inferable, via the raw image data. In instances where the framework 100 is implemented in a live imaging setting (e.g., on an image data processor associated with the image scanner), the imaging modality can be pre-configured. In other situations, where the process 200 is used in an environment with several types of imaging modalities being managed in a single processing environment, metadata information from the raw image data or manual user input may be used to identify the imaging modality associated with the raw image data.

Continuing with reference to FIG. 2, at step 210, one or more raw IQ features are identified based on the raw image data. The exact raw IQ features will depend on the imaging modality used to acquire the raw image data; however, there may be certain features that are common across all imaging modalities. The values of the raw IQ features may be determined using any technique generally known in the art. For example, image contrast may be determined using a technique such as the Weber method, the Michaelson method, or the standard deviation of the pixel intensities. The determined image contrast value can then be compared to a preset nominal value for contrast to create a raw IQ feature of “high contrast,” “low contrast,” or “nominal contrast.” At step 215, one or more user preferences are applied to the raw IQ features to identify a set of target IQ features for that user. As noted above with reference to FIG. 1, user preferences may be applied to the raw IQ features using a deep learning model trained based on previous feedback received from the user. Next, at step 220, processing parameters are determined based on the target IQ features determined at step 220. These processing parameters will depend on the exact algorithm being used to process the raw image data. Then, at step 225, the raw image data is processed to yield a final image customized to the user's preferences.

The generated image is presented to the user at step 230 in a feedback interface which is configured to allow the user to associate a preference indicator with the image. This preference indicator may then be used to refine the user preferences employed in the determination of the target IQ features. Additionally, in some embodiments, the feedback interface also provides a list of the IQ features used in the generation of the image. The user may then add new IQ features to be used in parameter generation. In some embodiments, the feedback interface may also be used to remove or modify existing IQ features for use in the processing of future images.
